SPECIFICATION forming part of Letters Patent No. 620,400, dated February28, 1899-.

Application filed August 18,1898. Serial No. 688,926. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDRECH AHRENS, a citizen of the United States,residing at New York, (Tarrytowm) in the county of Testchester and Stateof New York, have invented a new and useful Projectile for Use in NavalGuns and Artillery, of which the following is a specification.

My invention relates to improvements in armor=piercing projectiles bywhich a projectile smaller than the caliber of the gun is fired; and theobjectof my improvements is to provide a projectile which will have agreat penetrating power and capable of being thrown from the muzzle of agun to an exceedingly long range, and when a long projectile is usedpossesses the capability of being fired at a point below the waters edgewithout deflection. I attain these objects by the constructionillustrated in the accompanying drawings, in which Figure 1 is a sideview of the entire projectile; Fig. 2, a view of the rear or back plate;Fig. 3, a view in perspective of a section of the steel projectile,showing the rear end; and Figs. 4 and 5 are perspective views showingthe wooden jacket when open and separated.

Similar letters refer to similar parts throughout the several views.

The jacket J, Figs. 4 and 5, is composed of wood in two pieces, eachpart having the shape of a semicylinder, the two parts being heldtogether by two wooden pins 19 p, the front ends being slightlybottle-necked on the outside to insure easy entry into the breech of agun. This cylinder is made to fit the breech and may be made anyrequired size, The steel projectile fits inside the cylinder when thetwo parts are fastened together. The

front end of the jacket J is hollowed out in Figs. 4 and 5. The plate Pis also fastened to the jacket J by four screws 8.

When the projectile fitted together as in Fig. 1 is propelled from themouth of a gun, the force of the explosion and the air-pressure in thehollow end of the jacket created by its great velocity and the rotarymotion of the projectile will cause the jacket J to separate and the twopieces and the plate P to fall to the ground, while the steel projectileis propelled with great force at the object aimed at. The properaccuracy is obtained by the jacket J and the plate P re= ceiving arotary motion by passing through the rifiing of the gun-barrel. Theprojectile B may or may not have an explosive head.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

The combination with a projectile having a square rear end, of a woodenjacket, cylindershaped in two parts, hollowed out in the front, cut withmortises at the rear end, a steel plate having a square recess in whichrests the square end of the projectile and with ribs and lugs to enterthe mortises in the rear of the jacket, all substantially as set forth.

FREDRECH AHRENS.
